Answer to Question 1

ANS: B
A. Incorrect response: See explanation B.
B. Correct response: Unless the closed-circuit suction catheter is visibly soiled or known to be contaminated, it can be replaced on the same schedule as the ventilator breathing circuit.
C. Incorrect response: See explanation B.
D. Incorrect response: See explanation B

Answer to Question 2

ANS: B
A. Incorrect response: The hole at the tip of a suction catheter does not influence the vacuum pressure used for suctioning.
B. Correct response: In addition to facilitating the removal of secretions, the holes at the distal end of a suction catheter help prevent trachea mucosal damage. Without these side ports, the catheter tip would strip cells away mucosal tissues as suction is applied, and the catheter withdrawn.
C. Incorrect response: Under ordinary circumstances, a suction catheter is not inserted into the ETT when a chest x-ray is being taken.
D. Incorrect response: A suction catheter cannot damage an artificial airway.
